touch pad devices 10, constructed as above, have a problem in that they have a large number of components, including thetouch pad 13,touch pad housing 16,buttons 18, andpad board 19. This makes it difficult to manage them and lengthens the assembly process. - In particular, the
buttons 18 must be fastened to the lower surface of thekey deck 7 by screws or fixed thereto by thermal bonding. This means that a separate tool (e.g. driver) or thermal bonding equipment is necessary. - When the
buttons 18 are not firmly fixed to thekey deck 7 or become loose after a long period of use, theswitches 19′ may not be pressed as desired. This means that thetouch pad device 10 may fail to function properly. Since thebuttons 18 are positioned on the lower surface of thekey deck 7, they may detach from thekey deck 7 when repeated pressed by the user. - Accordingly, the present invention has been made to solve the above-mentioned problems occurring in the prior art, and an object of the present invention is to provide a touch pad device having a small number of components.

key deck 20 forms the exterior of the outer surface of the main unit of the portable computer. Although thekey deck 20 generally forms the exterior of the upper surface of the main unit, it may also form the front surface, rear surface, and parts of both lateral surfaces of the main unit. Thekey deck 20 has anelongated armrest 21 extending from the left to the right side of the upper surface of thekey deck 20 near the front end thereof. Thearmrest 21 supports the user's hands during input operation using akeyboard 22, which includes a number of keys for information input. - The
armrest 21 has atouch region 24 formed on an approximately central portion thereof. Thetouch region 24 is a part of the touch pad device and is adapted to make direct contact with the user's fingers. Thetouch region 24 may be a part of the surface of thekey deck 20 itself. Alternatively, a separate touch sheet (not shown) may be attached to thetouch region 24. This is because thetouch region 24, which makes direct contact with the user's fingers, may discolor depending on the material or surface treatment of thekey deck 20. Of course, the touch sheet must have sufficient resistance to discoloring or wear. - Preferably, the
touch region 24 is lower than the surface of thearmrest 21. This is for the purpose of preventing the user's hands, when resting on thearmrest 21, from making erroneous contact with thetouch region 24. - A
seating channel 26 is formed all around thetouch region 24 with a predetermined width. -
Penetration portions 28 are formed between thetouch region 24 and the front end of thekey deck 20 in theseating channel 26. Particularly, twopenetration portions 28 extend through thekey deck 20 side by side. - A
cover button 30 is seated in theseating channel 26 from above thekey deck 20 to cover thepenetration portions 28. The user directly presses thecover button 30 with fingers for operation. Thecover button 30 has the shape of an approximately square frame with a seam positioned halfway between thepenetration portions 28. Both ends of thecover button 30, which adjoin each other along the seam, form first andsecond button units - Push
buttons 32 are placed in thepenetration portions 28. Thepush buttons 32 are integrally formed on thekey deck 20 and positioned inside thepenetration portions 28. Eachpush button 32 is assigned to the correspondingpenetration portion 28. Thepush buttons 32 have apush protrusion 34 formed on the lower surface thereof, in order to push switches 44 (described later). - The
push buttons 32 are connected to thekey deck 20 by first andsecond connection legs connection legs connection legs - A
touch pad 40 is attached to the lower surface of thekey deck 20 in a position corresponding to thetouch region 24 and generates signals in accordance with user's input. In addition to thetouch pad 40, various components are mounted on the lower surface of thetouch pad 40. - A
board 42 is positioned adjacent to thetouch pad 40 on the lower surface of thekey deck 20. Theboard 42 hasswitches 44 mounted thereon, which are toggled on/off by thepush protrusions 34, as well as other components related to thetouch pad 40. Theboard 42 may be retained on the lower surface of thekey deck 20 or mounted on a bottom case (not shown). Theboard 42 is positioned so as to maintain a predetermined gap between theswitches 44 and thepush protrusions 34 of thepush buttons 32. - The operation of the touch pad device for a portable computer, constructed as above, will now be described in detail.
- The
touch pad 40 is attached to the lower surface of thekey deck 20 in a position corresponding to thetouch region 24 using double-faced tape, for example. Thecover buttons 30 is positioned in theseating channel 26 formed on the upper surface of thekey deck 20. Thecover button 30 may be attached to theseating channel 26 using double-faced tape, for example. - After mounting the
cover button 30 in theseating channel 26, the first andsecond button units corresponding push buttons 32 so that, when the first andsecond button units push buttons 32 are compressed accordingly. When the first andsecond button units push buttons 32, due to elastic restoration force. - The
board 42 is retained on the lower surface of thekey deck 20 or the bottom case with theswitches 44 mounted thereon, which are toggled on/off by thepush buttons 32. Theswitches 44 are positioned adjacent to thepush protrusions 34 of thepush buttons 32. - The touch sheet is attached to the
touch region 24 in accordance with design requirements. For example, double-faced tape is used to attach the touch sheet. The touch sheet is made of a material which is not easily discolored due to sweat, sebum, or cosmetics from the user's fingers. - After the touch pad device is assembled in this manner, the user touches the
touch region 24 with a finger to determine the position of the cursor and inputs the selected position by pressing the first andsecond button units - When the first and
second button units push buttons 32 are compressed accordingly and thepush protrusions 34 of thepush buttons 32 toggle on/off theswitches 44 of theboard 42. - The touch pad device for a portable computer according to the present invention is advantageous in that, since the push buttons are integrally formed on the key deck while being able to deform elastically, the number of components of the touch pad device decreases. This reduces the manufacturing cost.
- In addition, no tool or equipment is additionally necessary to mount the push buttons on the key deck. This makes the assembly process of the touch pad device simple.
- Furthermore, the gap between the switches and the push buttons can be set more accurately. Even when the push buttons are pressed repeatedly for a long period of time, they retain the initial position and maintain the operation reliability of the touch pad device.
- Although a preferred embodiment of the present invention has been described for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims.
- For example, although the
cover button 30 is formed all around thetouch region 24 in the above embodiment, it may just cover thepenetration portions 28 and thepush buttons 32.
